Abstract

A unilateral suspension arrangement for a fuel tank (3) on a side member (2) of a lorry is disclosed. The tank is mounted by means of a vertical U-section (1) on the side member (2). A channel-shaped element (13) is mounted on the tank, engaging a support section (14) on the side member. In order to prevent the tank against falling off during driving, the tank is provided with an angle bar (5) that engages a recess (6) on the vertical section (1).

With this suspension arrangement is achieved an easy mounting and at the same time a large useful volume of the tank (3) as the suspension arrangement is only located at the side of the tank, thus not limiting the useful height available under a platform body or similar resting on the side member (2).

Description

The present invention concerns a suspension arrangement for a container on a side member in a vehicle, preferably a lorry, the arrangement comprising a largely vertical support member mounted on the side member and including means for supporting the container.
Previously, containers in the form of fuel tanks, tool boxes, oil tanks, water tanks and the like have been disposed by unilateral suspension on the side member of a lorry under the platform body of the lorry.
In these arrangements according to prior art, the container has been fastened according to two different principles.
According to a first principle, the supporting means are formed by using an L-shaped bracket which is screw bolted on the side member via the vertical leg of the L thus constituting a vertical support member. The container is disposed upon the horizontal leg of the L. In order to have required strength, this L-shaped bracket has a relatively great height of between 5 and 10 cm. This causes a part of the space available under the platform of the lorry to be occupied by the horizontal leg of the L-shaped bracket resulting in less useful volume in the tank. This is a drawback.
According to another principle, a vertical support member in the shape of a U-section is screwed onto the side member. In this embodiment, a flat bar, which is welded onto the tank, is screwed on the U-shaped section at the top, and a plate is welded into the U-section at the bottom for supporting the tank at bottom. With this solution, a better utilisation of the space under the platform body is achieved so that the tank may have greater volume. However, in this system bolt extending all the way through the flat bars welded on the tank and through the plates welded on the U-section are used. This causes the mounting to be very difficult as the holes in the two plates in the U-section and the holes in the flat bars are to fit together by mounting. Even if close tolerances have been attained, mounting is still very difficult.
It is the purpose of the present invention to indicate a solution relieving these problems by providing an arrangement which in a simple way enables mounting of a container which may have a large effective volume in the space available under platform, or the like, resting on the side members of the vehicle.
According to the present invention, this is achieved with an arrangement of kind mentioned in the introduction which is peculiar in that the supporting means comprise a hooking means engaging a complementary hooking means which is mounted at a vertical side of the container as the two mutually engaging hooking means comprise an upwardly facing groove and a downwardly facing profiled edge arranged to engage the groove, and that at the vertical side of the container there is provided a projecting edge extending largely in parallel with the hooking means, and which may pivot into engagement behind a downwardly facing surface connected with the support member by pivoting the container about the mutually engaging hooking means.
By this arrangement, a new way of suspending the container is created where simple mounting is achieved and where simultaneously there is a useful volume corresponding to that which is known from the existing embodiment according to the above second principle. By using a hooking means on a vertical side of the container, it is possible to utilise all the height available under a platform body or the like as the container may be mounted with its upper side in level with the underside of the platform. The mounting occurs in a simple way by suspending the container on the mutually engaging hooking means. Then the container is pivoted by its own weight to its mounted position where the surface interacting with the projecting edge is provided by a recess at the upper or lower end of the support member. Alternatively, the surface may be provided on a screw or corresponding fastening means connected with the support member. Hereby is safeguarded that the container does not fall off due to jolting of the vehicle. In a simple way, this is further ensured by means of a single bolt through the projecting edge and the support member.
According to a specific embodiment of the invention, the arrangement is peculiar in that the hooking means comprise a quadrangular section fastened at an upper end of the vertical support member and engaging a U-section on the container with the open part of the U facing downward, the support member comprising one or more juxtaposed vertical U-sections that have a downwardly facing surface at each their lower end, the surface formed in a recess arranged to receive an angle bar which is fastened at the bottom of the container. The arrangement may be further peculiar in that the vertical U-sections are fastened with screw bolts on a C-shaped side member, and that one leg of the angle bar is welded onto the bottom of the container, and that the other leg, which protrudes outside the vertical side, is brought into contact with the bottom of the recess and is fastened with screw bolts to the vertical U-sections. This embodiment is particularly simple to make and to mount in connection with metal containers such a fuel tanks.
According to a further embodiment, the arrangement is peculiar in that the hooking means comprise quadrangular section fastened at a lower end of the vertical support member and engaging a U-section on the container with the open part of the U facing downward, the support member comprising one or more juxtaposed, vertical C-sections that each have a hole formed in the upper part of the side member and in line with a hole in a plate fastened at the top of the container, and that a screw bolt through the holes fastens the container. This may be an advantage when the hooking means are desired to be at the lower end of the vertical support sections.
Alternatively, the arrangement may be peculiar in that the hooking means comprise a V-shaped groove provided at an upper end of the vertical support member and engaging a V-shaped section with a downward facing edge, the support member comprising one or more juxtaposed vertical U-sections each having a surface at their downward facing ends formed in a recess which is arranged for receiving an angle bar fastened at the bottom of the container. This embodiment causes that the hooking means automatically slide into engagement and simultaneously enable a wedge action as the triangular section slides down into the groove.
Other embodiments of the hooking means are possible. It is only important to ensure that the hooking means are disposed on the side member and the container so that the upper side of the container and the side member are largely in the same horizontal plane when the hooking means are engaged. Also, it is advantageous if the hooking means are elongate and have a length corresponding to the length of the mentioned vertical side of the container. Hereby a great load may be carried by the hooking means.
The invention will now be explained in more detail with reference to the accompanying drawing where:

Fig. 1: shows a partial section through a first embodiment of an arrangement according to the invention,
Fig. 2: shows a view corresponding to Fig. 1 for illustrating a further embodiment of an arrangement according to the invention,
Fig. 3: shows a partial view for illustrating a further embodiment of the invention with a suspension arrangement based on the same principle as illustrated in Fig. 1, and
Fig. 4: shows a partial view for illustrating a further embodiment of the invention with a suspension arrangement based on the same principle as illustrated in Fig. 2.

In the subsequent Figures, corresponding or identical elements are provided with the same reference numbers, and no detailed explanation in connection with each single Figure will be given.
The arrangement shown in Fig. 1 comprises a vertical U-section 1 screwed onto a lorry side member 2 as in the case of the prior art arrangements. At the bottom 4 and in longitudinal direction of the container, which is shown as a tank 3, an angle bar 5 is welded on. This angle bar engages a recess in the U-section 1. Hereby is ensured that the tank cannot fall off as the recess has a downwardly facing surface 7 covering a vertical leg 8 of the angle bar 5. The angle bar may be screwed into the U-section by means of bolts 9 for further safeguarding against the tank falling off during driving.
At the top 10 of the tank 3 is welded a reinforcing plate 11 which at its outer end 12 is provided with a U-section 13 extending along the tank. This U-section grips as a hook down on a support section 14 fastened at the upper side of the U-section 1.
With this construction is achieved an easy mounting as the tank is hooked firmly on the U-section 13 over the support section 14. Then the tank is aligned in longitudinal direction until a hole 15 in the welded angle bar 5 is opposite to a corresponding hole 16 in the U-section 1. Then one or two bolts 9 may easily be used for clamping the angle bar and the U-section.
In Fig. 2 is shown an alternative embodiment of the arrangement. This embodiment differs from the embodiment in Fig. 1 by the horizontal U-section 13 and the support section 14 being disposed at the bottom 4 of the tank 3 as the support section 14 via an angular bracket 17 is mounted at the lower end of a U-section 18 which is shown with a downwardly directed tapering and is appearing at the underside of the side member 2. The mounting may occur by screw bolting, welding, or in other ways.
At the top 10 of the tank is welded a connecting plate 19 extending beyond the side member 2. The connecting plate is provided with a hole 20 which is brought to a position at a hole 21 in the side member 2 after which a bolt 22 is used for fastening the tank.
In this situation, the tank is thus placed by hooking the U-section 13 over the support section 14 and then pivot the upper part of the tank inwards so that the plate 19 is over the side member 2. Then the tank is aligned longitudinally until the holes 20 and 21 are corresponding with each other.
In Fig. 3 is shown a partial illustration of a further embodiment. Only the upper part of the tank is shown as the lower part of the tank will correspond to the embodiment shown in Fig. 1. This embodiment differs by reinforcing plate 11 being provided with a section 23 with a profiled V-shaped edge 24 at its outer end. This V-shaped edge engages a corresponding V-shaped groove 25 provided at the upper side of a section 26 which is fastened to the side member 2 by means of bolts 27. Thereby the V-shaped part 24 is easily hooked and brought into engagement with the V-shaped groove 25 and will automatically be leading into abutment against the side member 2. An angle bar 5 (see Fig. 1) ensures that the tank does not fall off during driving.
In Fig. 4 is shown a further embodiment. Here is shown hooking elements corresponding to those shown in Fig. 3. However, here they are provided at the bottom 4 of the tank 3. At the upper end of the tank there is provided a plate corresponding to the plate 19 in Fig. 2 for similar fastening of the tank on the side member 2.
In Fig. 2, the safeguarding of the tank against falling off during driving is provided by means of the bolt 20. Thus the underside 28 of the bolt head will form a surface for engaging the connecting plate 19. As alternative to the use of holes 20 in the plate 19 and the side member 2 there may be used an elongate opening in the side of the plate 19 and/or the side member 2. A corresponding safety device (not shown) is used in the embodiment shown in Fig. 4.
